1.
For each Theater, multiple audio Pro les can be created. A Pro le is the combination of the Speakers
de nition (mutiways, levels, delay), Bass Management, Manual EQ and a Dirac lter design if applied
(see part 6).
2.
We o er two approaches to Bass Management. A rst one that is the Standard Bass Management
as speci ed by Dolby and a second one that is a Custom Bass Management which opens up full access
to how the Bass should be managed/redirected in the system. The Custom mode has been designed for
installation where main channel speakers are used to reproduce the Bass. At this stage, you should select
which mode you want to use, considering that going from one mode to the other will reset the adjustments
made. To help you on this decision, the two modes are described in the next pages.
3.
Adjust the crossover lters (Low, Middle and High) of LCR Multiways Speakers with cut-o frequency,
slope and phase. For more than three ways, additional lters can be adjusted via the Manual EQ (see 5.10).
4.
With Manual EQ and the Dirac Filter Design corrections applied, the average output level in the Theater
might be lowered signi cantly. You can boost this average output level between 0 to 12 dB, in 3 dB steps.

Note that setting a too high level can lead to clipping.
